I think there's a science to the day about conception. Even if you took one extra day to deliver, or if your baby was ready one day earlier than the next person, that would set your dates differently. I don't think it is super important, anyway, if you are trying to conceive again and you want to calculate around your past success, 4 days up or down are within the parameters of what is considered the ovulating dates. So, you have to try,try,try,try,tryyyyy for all days around your cycle!! :)

There is no exact way to know. A woman is not pregnant for precisely 40 weeks. Some women deliver on 39w4d and some on 42w2d. You can get an approximate idea, but unless you were TTC and monitoring your ovulation, you will not know for sure.

Go to pregnology.com and click on "How far along am I?" It'll calculate everything, even if you've already had your baby. I used it with my first son and found out that we'd concieved him on my husband's birthday! (Talk about a birthday suprise!)
